Description
Technical field
The present invention relates to the method for phenol in a kind for the treatment of of dyeing and printing, belong to sewage treatment area.
Background technology
In recent years, the product category that printing and dyeing enterprise manufactures gets more and more, and except production method difference, fibre composition also has larger change, especially in recent years the fast development of man-made fiber, so the waste water quality of discharging in its production process also usually changes.Dyeing waste water color-variable, colourity is high, enters river enter blackening in river, colourity is one of major control index of dyeing waste water, and cause the major cause of color degree of dyeing waste water to be dyestuff, they are in the transitory stage of Substance Transformation, character extremely unstable, COD value is very high.According to statistics, whole world Textile Dyes to produce more than 40 ten thousand tons, more have 10%-20% dyestuff to enter waste water in dyeing and printing process process and enter water body, the dyestuff in waste water can absorb light, reduces water transparency, oxygen in a large amount of consumption water, destroy self purification of water body, this waste water if do not processed, then can produce larger Organic to receiving water body and pollute, be that the ecosystem produces larger destruction, therefore the improvement of dyeing waste water is imperative.
Phenol many employings physico-chemical process, biological method and electrochemical method in current treatment of dyeing and printing, conventional physical chemistry method has ion exchange method, ultrafiltration, membrane technique etc.; Chemical method is as Coagulation Method, oxidation style, electrolytic process etc.; Biological process has anaerobic-aerobic technique etc.; find out from Some Domestic dye processing plant waste water treatment process and effect; adopt traditional materialization, the biochemical more difficult unification reaching removal effect, Financial cost, ecological protection of method dye wastewater treatment, colourity is still not easily up to standard simultaneously.And electrochemical process power consumption is large, electrode materials consumption is too much, when reactant concn is not high, the treatment time extends, current efficiency ground.Therefore these methods all can not be removed well.
Summary of the invention
To the present invention is directed in traditional materialization, biochemical method treatment of dyeing and printing that phenol is more difficult reaches removal effect, thus propose that a kind of removal effect is high, Financial cost is low, have the method for phenol in the unified a kind for the treatment of of dyeing and printing of protecting ecology.
In order to reach above-mentioned purpose, the concrete technical scheme of employing is:
(1) accurate measuring 1.3L concentration is the hydrogen peroxide of 20mg/L, 0.05g potassium oxalate, adds 2.0L deionized water wiring solution-forming;
(2) above-mentioned solution is placed in ultrasonic acoustic, and regulates ultrasonic frequency to be 600HZ, under hyperacoustic effect, shake 0.5-1.0h;
(3) in mixed solution, 0.05kgFe is added again subsequently
2o
3, and be 3.0-3.5 with salt acid for adjusting pH;
(4) start electron excitation device simultaneously, regulate ultrasonic frequency to 800HZ, under ultraviolet lamp, irradiate 2-3 hour;
(5) leave standstill, after 0.5-1.0h, add the activity charcoal powder of 2-3g supported catalyst, the catalyzer of load on described activated carbon powder is copper-Pt Rh alloy, and its mass ratio is for respectively to account for 1/3rd.
Application method of the present invention is: draw above-mentioned mixing solutions, joins in the dyeing waste water containing phenol, and the amount added is 100-200mg/L, and opens ultraviolet lamp simultaneously, stirs, reaction 10-15min.
The significant advantage that the present invention has is:
(1) be raw material with hydrogen peroxide, mix with gac, to adopt with Ultrasonic Conditions in conjunction with coefficient method, phenol in wastewater is processed, greatly improves the degradation rate of phenol;
(2) iron protoxide ferrous ions and hydrogen peroxide can form Fenton reagent, Pyrogentisinic Acid can carry out advanced treatment, and treatment effect are obvious under not being acidic conditions;
(3) in whole reaction process, intermediate product ferric oxalate complexes under illumination condition, degradable, and mixed solution can process phenol again, energy-conservation, economic environmental protection.
